There must be some Tolkien geeks here who can answer a question I’ve had for quite a while.
When Smaug is headed to Laketown, they cut the bridge. Why?
The narrator tells us that if Smaug fell into the water the lake would quench him, but surely he could fly from the land to the island without having to rest on the bridge. He flew all the way from the mountain, after all. The lake couldn’t be that large.
